Wolman 1901A Woodlife Coppercoat Green Wood Preservative gal

This is so hard to find on the shelves here in Maine, so I was glad that DTEP had it available for a reasonable price. I have used almost 2.5 gallons of this stuff for my deck rebuild and wouldn't trust any other product to protect the end grain of my joists, ledger, posts, and boards. The smell is a bit strong, but it dissipates quickly as does the green tint. It cleans up easily with soap and water, too. Just grab a cheap chip brush and apply it liberally to the end grain of any cut PT wood, letting it soak in as best as you can. You'll be thankful you did when you don't need to replace the frame of your deck the next time you replace your PT decking boards. HIGHLY RECOMMENDED.
